There are times when you can be absolutely certain that the Orioles are going to lose a ballgame. Today, perhaps that moment of realization hit you when the O’s were shut out for eight innings by a pitcher with a career 4.56 ERA. Or it may have slapped you in the face when the Orioles somehow got a runner thrown out trying to score from third base — on a single. But it became official when Nate Lowe smacked a walkoff hit in the bottom of the 10th, averting the Orioles’ attempt for a three-game sweep in Texas with a 1-0 decision.
